ABSTRACT:Nutrition is a basic human need and a prerequisite to a healthy life. In India about 35 percent of total population consists of children below 15 years of age. Malnutrition is the most wide spread condition affecting health of the children, there is an urgent need to institute supplementary feeding programmes in the developing countries. Hence the investigator had undertaken this study to evaluate the effectiveness of Krishna Poshak Mix on nutritional status of rural anganawadi children of Pedaparimi village, Mangalgiri Mandalam, Guntur district, Andhra Pradesh.” Methodology: A true- experimental, pre-test post-test control group research approach was adopted as research design in this study. Fifty subjects were selected by using simple random sampling technique who were assigned into Experimental group (n=25) and control group (n=25). Findings: The results of the study revealed that Krishna Poshak mix laddus were effective in improving the nutritional status of the preschool children. As it was evidenced by their improved mean values form the initial assessment of weight (12.72) and UMAC (13.16) in experimental group and in control group weight (12.01) and UMAC (12.91) to after 6 weeks assessment of weight (13.31) with ‘t’ value (29) and UMAC (13.6) with ‘t’ value (17.4) in experimental group and the control group mean values of weight (12.04) with ‘t’ value (0.54) and UMAC (12.91) with t’ value (1) which shows statistically significance association at p<0.05 level. Conclusion: The overall study findings concluded that KPM laddus as supplementary nutrition is an effective strategy which can help in improving anthropometric measurements of children and this can indirectly help to reduce the mortality and morbidity rate among the preschool children by recuperating the immune levels.
